You design a Business Intelligence （BI） solution by using SQL Server 2008. You create a SQL Server 2008 Reporting Services （SSRS） solution by using SQL Server 2008. Several reports on the server use a shared data source named DSProduction. You modify an existing report that uses the DSProduction data source. After deployment， the modified report must use an alternate data source. You need to prevent the modified report from affecting other reports. What should you do？（）

• A、 Update the connection string of the DSProduction shared data source to point to the alternate data source.
• B、 Update the modified report to use a report-specific data source. Update the connection string of the report-specific data source to point to the alternate data source.
• C、 Create a new shared data source named DSProduction in the same folder as that of the modified report. Update the connection string of the new shared data source to point to the alternate data source.
• D、 Disable the DSProduction data source. Update the modified report to use a report-specific data source. Update the connection string of the report-specific data source to point to the alternate data source.
